1.Easy
P = 80 kNABsection3 m3 m

Find the bending moment Mx at the section x = 3 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 6 mP = 80 kN at 3 mx = 3 m
Mx = kN·m
2.Easy
w = 6 kN/mAB10 m

The simply supported beam carries a uniformly distributed load w over its whole span. Find the maximum bending moment Mmax in the beam.

L = 10 mw = 6 kN/m from 0 to 10 m
Mmax = kN·m
3.Medium

  1. 1A (x = 0 m)
  2. 2B (x = 1 m)
  3. 3C (x = 2 m)
  4. 4D (x = 3 m)
  5. 5E (x = 4 m)
  6. 6F (x = 5 m)
  7. 7G (x = 6 m)
4.Medium
w = 5 kN/mABsection3.5 m2.5 m

Find the bending moment Mx at the section x = 3.5 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 6 mw = 5 kN/m from 0 to 6 mx = 3.5 m
Mx = kN·m
5.Hard
w = 3 kN/mABC8 m1 m

The beam rests on a pin at A and a roller at B and overhangs B by 1 m to the free end C. A uniformly distributed load w acts over the whole length A–C. Find the maximum sagging bending moment Mmax between the supports.

L = 9 mw = 3 kN/m from 0 to 9 msupports at x = 0 and x = 8 m
Mmax = kN·m
6.Hard
w = 5 kN/mP = 15 kNABsection1.5 m2.5 m

Find the bending moment Mx at the section x = 1.5 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 4 mP = 15 kN at 1.5 mw = 5 kN/m from 0 to 4 mx = 1.5 m
Mx = kN·m
